First Philippine record of the parasitoid,Comperiella sp. (Hymenoptera: Encyrtidae): a potential biocontrol agent against Aspidiotus rigidus (Hemiptera: Diaspididae)

The encyrtid genus Comperiella Howard has so far not been reported in the Philippines, where there is currently an outbreak of the coconut scale insect Aspidiotus rigidus Reyne particularly in the southern parts of the island of Luzon and in some areas in Mindanao. Among Comperiella species, only C. unifasciata Ishii has been reported as a parasitoid of A. rigidus. We report not only new sightings of this parasitoid genus in the Philippines from surveys conducted in parts of the provinces of Laguna and Batangas, but also the discovery of a possibly new species that, like C. unifasciata, has been found to parasitize A. rigidus at a high rate. These findings have presented a potential of biological control against the coconut scale insect problem that has threatened the coconut industry in the country.

Seladonia (Pachyceble) henanensis sp. n. (Hymenoptera,Halictidae) from China

Seladonia (Pachyceble) henanensis sp. n., is described from Henan Province, the eastern-central part of China. This species is separated from its allied species by a combination of the following morphological characters: head broad in female, inner hind tibial spur of female with 7–8 slender teeth, T1 basolaterally with appressed hair tuft in both sexes, and genitalia with long and large lower gonostylus in male. Important taxonomic characters are illustrated with photographs, scanning electron micrographs, and line drawings.     

Description of Dolichodorus grandaspicatus n. sp. (Nematoda: Dolichodoridae)

Dolichodorus grandaspicatus n. sp., collected from soil about roots of a red maple (Acer rubrum L.) in a creek bottom near Ludwig. Johnson County, Arkansas, is described. It differs from two closely related species, D. marylandicus and D. heterocephalus, by the longer spike on the female tail, the lenght of the female tail, and the shape of the extrudable portion of the gubernaculum of the males. It further differs from D. marylandicus by having heavily sclerotized accessory pieces of the vuvla and from D. heterocephalus by having a shorter stylet.     

Morphology and infraciliature of two new marine urostylid ciliates: Metaurostylopsis struederkypkeae n. sp. and Thigmokeronopsis stoecki n. sp. (Ciliophora, Hypotrichida) from China

ABSTRACT. The morphology and infraciliature of two new marine urostylid ciliates, Metaurostylopsis struederkypkeae n. sp. and Thigmokeronopsis stoecki n. sp., collected from the coastal waters off Qingdao (Tsingtao), China, have been investigated. Metaurostylopsis struederkypkeae n. sp. is characterized by the slender body shape, small size, rose-reddish cell colour, and having two kinds of pigment-like granules. The larger pigment-like granules are yellow–green or grass-green in colour, oval in shape, and flattened, whereas the smaller ones are wine-reddish. Infraciliature and nuclear apparatus are similar to the well-known Metaurostylopsis marina. Thigmokeronopsis stoecki n. sp. is characterized by its large size with dark brown cell colour and grass-green cortical granules, which are large, blood-cell shaped, and sparsely distributed. The thigmotactic ciliature is conspicuous: 11–14 rows of densely arranged cirri occupy the most postoral area. Keys are provided for all the known species in both genera.     

Description of Pararotylenchus belli n.sp. (Nematoda:Hoplolaimidae)

A new species of Pararotylenchus Baldwin &Bell, 1981 from the Pacific coastal area of California is described. Numerous females and juveniles were recovered, but no males were found. Pararotylenchus belli n.sp. is most similar to P. sphaerocephalus, but females of P. belli are shorter and have a shorter stylet and a hemispherical tail. Specimens from a cereal field in South Dakota were identified as P. colocaudatus.     

Description of Pratylenchoides sheri n. sp. (Nematoda: Pratylenchidae)

Pratylenchoides sheri n. sp., a bisexual species from the Pacific coastal area of California, is described and illustrated. Its most distinctive characters are the esophageal glands slightly overlapping the intestine dorsally, the large ventrally slanting esophago-intestinal valve, the lack of labial sectors in the first lip annule, the presence of males, and apparently functional spermatheca. Pratylenchoides sheri is morphologically similar to P. magnicauda, but differs in length and labial conformation, its more anterior vulva, and the presence of males. Relationships of head and esophagus gland lobe characters of P. sheri are compared to other Pratylenchoides species.     

First record of the myrmicine ant genus Carebara Westwood, 1840 (Hymenoptera, Formicidae) from Saudi Arabia with description of a new species, C. abuhurayri sp. n

The myrmicine ant genus Carebara is recorded for the first time in Saudi Arabia from the Arabian Peninsula as a whole. A new species Carebara abuhurayrisp. n. is described based on workers collected from Al Bahah region. One of the smallest ant species known to occur in Arabia, Carebara abuhurayri is found in an area inhabited by many ant species including Tetramorium sericeiventre Emery, 1877, Pheidole minuscula Bernard, 1952, Pheidole sp., Monomorium destructor (Jerdon, 1851), Monomorium exiguum (Forel, 1894) and Monomorium sp. and Crematogaster sp.     

Description of Crassolabium persicum sp. n. (Nematoda, Dorylaimida, Qudsianematidae), an interesting species from Iran

A new species of the genus Crassolabium, Crassolabium persicumsp. n., collected from Arasbaran rangelands of Iran, is described and illustrated. It is characterized by its body 1.92-2.40 mm long, lip region offset by constriction and 17-19 μm wide, odontostyle 16-19 μm long with aperture occupying less than one-third (27-30%) its length, neck 428-690 μm long, pharyngeal expansion 369-390 μm long or occupying 54-56% of total neck length, female genital system amphidelphic, uterus bipartite and 162-218 μm long or 2.3-3.5 times as long as body diameter, pars refringens vaginae well developed, V = 54-57.5, vulva longitudinal, prerectum bearing a blind sac, tail conical with rounded tip to conoid (25-36 μm, c=60-69, c'=0.5-0.9), spicules 68-72 μm long, precloacal pair of supplements far (22-27 μm) from cloacal aperture, and 13-17 shortly spaced ventromedian supplements with hiatus. The new taxon is compared in depth to its relatives in Crassolabium as well as other similar species of Aporcelaimellus and Amblydorylaimus.     

Morphology and Molecular Phylogeny of Two New Marine Euplotids,Pseudodiophrys nigricans n. g., n. sp., and Paradiophrys zhangi n. sp. (Ciliophora: Euplotida)

ABSTRACT. The morphology, infraciliature, and molecular phylogeny of Pseudodiophrys nigricans n. g., n. sp., and Paradiophrys zhangi n. sp., isolated from a sandy beach near Qingdao, China, were investigated. Pseudodiophrys is characterized by the Diophrys‐like ciliature pattern, but having only a single, reduced undulating membrane. Pseudodiophrys nigricans, the type species by monotypy, is described from live and silver‐impregnated specimens. Paradiophrys zhangi is similar to the type species Paradiophrys irmgard but can be recognized by its border body and the number (7 vs. 8–10) and arrangement (in rows vs. sparsely distributed) of the frontoventral cirri. Small subunit (SSU) rRNA gene sequence data support the validity of both species. Phylogenetic analyses based on the SSU rRNA gene sequence data currently available for uronychiids and other related taxa indicate that P. nigricans is most closely related to Diophrys scutum and Diophrys apoligothrix, while P. zhangi clusters most closely with Apodiophrys ovalis within a clade that also includes two other Paradiophrys species.     

Nematode parasites and associates of Dendroctonus spp. and Trypodendron lineatum (Coleoptera: Scolytidae), with a description of Bursaphelenchus varicauda n.sp.

Nematode parasites and associates of four bark beetle species in British Columbia were surveyed. Bursaphelenchus varicauda n.sp., Ektaphelenchus macrostylus, Panagrolaimus dentatus, and Cryptaphelenchus latus were found associated with Dendroctonus pseudotsugae. Parasitorhabditis obtusa was found in the gut and Contortylenchus reversus in the hemocoel of both D. pseudotsugae and D. rufipennis. The latter also had hemocoel infections of Sphaerulariopsis dendroetoni, which were not found concomitant with C. reversus infections. Contortylenchus brevicomi occurred in the hemocoel of D. brevicomis. The first report of a tylenchid larva parasitizing Trypodendron lineatum in North America is presented. Bursaphelenchus varicauda n.sp. was obtained from the gallery frass of D. pseudotsugae. It resembles B. corneolus and B. bestiolus but differs from the former species in female tail shape, the position of the excretory pore, spicule shape, and position of the male caudal papillae, and from the latter species in spicule shape and in the length of the esophagus and postuterine sac.     

Leptojacobus dorci n. gen., n. sp. (Nematoda: Diplogastridae), an Associate of Dorcus Stag Beetles (Coleoptera: Lucanidae)

A new species of diplogastrid nematode, Leptojacobus dorci n. gen., n. sp., was isolated from adults of the stag beetle Dorcus ritsemae (Coleoptera: Lucanidae) that were purchased from a pet shop in Japan. Leptojacobus n. gen. is circumscribed by a very thin, delicate body and by a small stoma with minute armature. A combination of other stomatal characters, namely the division of the cheilostom into adradial plates, the symmetry of the subventral stegostomatal sectors, and the presence of a thin, conical dorsal tooth, further distinguishes Leptojacobus n. gen. from other genera of Diplogastridae. Phylogenetic analysis of nearly full-length SSU rRNA sequences support the new species, together with an isolate identified previously as Koerneria luziae, to be excluded from a clade including all other molecularly characterized diplogastrids with teeth and stomatal dimorphism. Therefore, the new species will be of importance for reconstruction of ancestral character histories in Diplogastridae, a family circumscribed by a suite of feeding-related novelties.
